29 reviews for Custom Athletic Mouth Guard

A good mouthpiece is everything. I can’t play right without one. I gotta be able to focus on the game and custom made is the only way I can do that. Love that fit!

I’m saving up for the full wrap design but for now just to have a quality mouthguard is enough for me. I absolutely love it! Will be back for more!

I play roller derby and we have to be able to communicate. Also, we get in trouble if they catch us taking our mouthguard out (which is inevitable if its uncomfortable). I’ve gone through so many brands and Sentinel is by far the best. Through and through just a great company. The customer service was perfect, professional packaging, instructions that make sense, and a quality product. Couldn’t ask for more. Good job guys!

Was nervous I wouldn’t be able to take my own dental impression but after being quoted $250 at the dentist I thought I would give this a try. So glad I did! Best mouth guard I’ve ever owned!!

I wanted a better mouthguard than a store bought one to use while playing hockey, I kept gagging on my boil and bite when I would skate hard and its started to get really annoying. My buddy told me he got one from Sentinel and to try them out. Happy I did, totally worth it! its fits great and easy to breathe!

This is my first time using Sentinel but my 4th custom Mouthguard and its by far the best one out of the 3 that I’ve had.. Hands. down. Its not super bulky or cheap feeling. My others would hurt my mouth after about an half an hour from being stretched out. I can breath a lot better, I can drink water without taking it out, and I can speak clearly. I highly recommend Sentinel.

Just bought two more for my little cousins for Christmas. I’ve had mine for about 5 months now. I used to go through the $5 ones every week!

Had a little trouble getting a good mold of my teeth the first time around but Sentinel sent me another kit right out. I had been using cheap store bought guards for years. I’ll never wear anything but custom from now on. Huge difference.

Got my mouth guard today. I’ve never had a better fit. It’s not bulky at all. I can talk with it in, & drink water. Can’t wait to use it at practice tonight! Thanks Sentinel!

Fast shipping and very easy to deal with it, Extremely happy with Sentinel Well done! A+++

Honestly I dont know why people waste their money on over the counter guards. I will always buy custom and recommend them to everyone I come across. here’s some things to consider.

you can Breathe Better, You can actually talk with it in your mouth and you can drink water without taking it out!

plus it has a really good warranty, I seriously promote this company so much… they should hook me up with a free one! hahah

I needed an extra thin mouthguard because I’m not competing in a contact sport (just dance- I have veneers). I got a thin clear guard and you can hardly tell I have anything in my mouth. Wonderful job! It’s exactly what I wanted.

So nice to have a mouth guard I can actually wear! I’ve gone through a gazillion store bought ones and this is by far worth every penny. Two thumbs up! -Kirsten

Great Mouthguard. I use it for football. It stays in place. I actually have to pop it out with my fingers after practice. I’m QB so I need to communicate. Perfect for me. Thanks!

Sandip Yucan – December 6, 2014:

Didn’t follow the directions well enough the first time around and messed up my mold. Contacted Sentinel and they were super nice! Sent another putty kit right out. I got it the second time! My mouthguard fits flawlessly. Thank you!! A+++++++++

Brad Cleckler – December 6, 2014:

Man I did not know what I was missing. Everyone told me to go custom fit but I thought my chewed up, germ infested one from Academy was pretty good lol. You can’t chew on this! It stays up there locked onto my teeth until its ready to come down. Amazing!! So comfortable. The difference is just unbelievable. Thanks Sentienl Team! Great staff btw

Richard H. Cassidy II – May 20, 2015:

A common question I am asked from other fighters is if the mouth guards are breathable and if they’re thin or bulky. The answer is definitely yes they are extremely easy to breath and talk with, and you can get your mouth guard made as thick or thin as you want. I prefer the 2mm thickness. It’s not bulky at all and I still feel protected.

Danny Matchett – Oklahoma – September 20, 2015:

Aside from unbeatable comfort, the second best aspect of the Sentinel mouth guards is that you can customize them to any color you desire. You can have your name imprinted on them or your team name and colors. I still have my first mouth guard that I ordered from Sentinel in 2011 (just a plain dark blue) and just had a second one made in honor of my dad. I recommend you guys all the time. You’re the best!

Daniel S. – June 26, 2017:

As a professional fighter I’m always looking for good solid gear that can last through intense training while giving the comfort to focus on what I need to do. The fit is excellent. The guys at Sentinel are great too. Easy company to work with. I’ve ordered a few guards over the years. Can’t beat the fit.

Patrick Thompson – February 13, 2018:

I have spent a small fortune on mouth guards at Dick’s sporting goods. I’ve tried all kinds of different brands. Some are decent but the problem is, none of them last. I end up replacing them after a few months. This guard is the real deal. I don’t chew on this one (which is a first for me) because the material is not as soft as the ones you buy at Dick’s and it stays in place so it’s not hanging down. I like that Sentinel keeps my mold on file so that I can reorder in the future. Really nice guard and good price. I will recommend them to anyone.

Sean Hilditch – May 5, 2018:

I’ve played Hockey since I was little and have always hated buying mouth guards. They;re uncomfortable and I get yelled at for not having it hang out of my mouth. This is the first guard that has actually fit correctly. There is nothing that comes close to this fit and it’s impossible to have this one hang out of my mouth because I have to physically remove it by popping it off of my back teeth. No comparison. 5 stars and highly recommended!

Vincent Giordano – July 3, 2018:

The best on the market!! I couldn’t pass on the great price these were being sold for. I followed instructions for taking my teeth mold they gave me and ordered a blue mouthguard. When I got the guard I knew it would fit well but the fit is far better than I imagined. It’s not too bulky. It feels good in my mouth. Very uncomfortable. Even wearing it while talking is easy. Again, very uncomfortable. Thank you.

Ryan Fox – August 26, 2018:

These Sentinel Mouthguards are without a doubt the best mouthguard I have worn. I’ve been a customer since 2013. They fit perfect and are unbelievably comfortable. The design is great and the color really pops. The quality of the material is very, very high and the quality of the overall product is extremely high. I will never purchase another brand of mouthguard. They are perfect to wear during Muay Thai, Boxing, MMA, Jiu Jitsu, Wrestling or any other kind of combat sport or just to work out in. A+++++

Frédéric – March 30, 2019:

Its better 2 or 3 mm for the thick?

Asmi234 – April 1, 2019:

Hi there!

For full contact sports we suggest a 3mm thickness. 2mm is thin and best for non contact sports. Please let us know if we can help further.
